I came across this ebay ad for an El Dorado
bus with a Cummins engine
4614046067
If you scroll down the photos, there are some pictures of the engine... obviously no big belt running off to a radiator fan, in fact no obvious means of running a radiator fan at all...
however farther down there is a photo of some massive DC motors running two nasty looking fans.
Have they finally done the impossible? (although I bet this bus only saw "shuttle" work at a flat airport and never had to take a 6% grade if it really is so...)
Anyone know about these busses? Is that set of fans perhaps the AC instead? It may be, since if you look closely there apears to be a second alternator belted to the big AC pump (which would make sense- if those fans were for the AC, they would only be needed when the compressor is on)
...but then looking at the outside of the bus, there are only two grilled areas, one on the right rear and one on the left rear, nowhere else for a separate AC radiator...
So is the engine fan is driven some other magical way? or did someone finally do it....

Those are the A/C fans, located in the compartment above the engine.
IIRC, these El Dorado National Escort RE-As use a hydraulically-driven fan.
Gary, why don't you call El Dorado and ask how they drive the engine cooling fan? The plant where they build these is in Riverside, not that far from you: 909-591-9557.

Just guessing, that rear view looks about exactly like my Executive Industries Motor Home. On mine they put the radiator up front where it belongs, 70 ft of 1 1/2 copper pipe up and back is probably enough to cool that little 5.9 Cummins without the radiator. Might just be those little slits below the bumper is the grille! |

We have a National (Eldorado) that looks very similar only it's built like an innercity (huge luggage bays and one door in the front). Those two fans are AC, they are mounted behind that grill directly above the engine compartment. The radiator is on the left side, cooled by a large hydraulic fan. |

I have stayed out of the electric fan squabble on purpose, but an now ready to comment. In many cases electric fans will work and I say this because in many cases no fan is needed.
I have an 8V92DDEC in a 45,000 pound Newell with the radiator on back. Last summer I installed a Horton fan clutch and from MN to TN to AZ the fan egaged for less than 15 minutes, and this was in low and slow driving.
The natural draft pocket behind the radiator was enough to pull all the air thru that was needed to cool. Granted on this trip there was no major hill climbing needed. Just 40 plus mph head winds across TX and NM on I40.
So it depends on your natural air movement. GM put the mud flab behind the tires and in front of the engine. This also created a natural draft thru the radiator, unless you put a skirt on. GM buses fan seldom would lock up to give full speed. The only time I saw that on our 4106 was when we had a skirt and bad radiator and hill climbing. |

I should point out that you do have to plan on worst case, even if it selcom occurs. |

Yup Gary, I agree, it depends on the driving.
I also put a Horton clutch in, and around San Diego even in the summer it rarely comes on ever, even going up grades.
BUT when I take it up to 8000 feet in high desert and am running on flat ground at 75, outside it's 95-100, the fan runs almost continuously... |
